Who Can Be a Trustee in Ontario? Eligibility and Practical Considerations

Naming a trustee is one of the most consequential decisions in setting up a trust, whether it is a family trust created during your lifetime or one that will only take effect through your will. The legal bar for who can serve as trustee in Ontario is low. The practical bar for who should serve is much higher.

This article separates the two: the minimum legal requirements to hold the role, and the practical factors worth thinking through before you actually name someone.

The Legal Minimum: Who Ontario Law Allows

Ontario law does not require a trustee to hold any particular licence, credential, or professional designation to manage a private family or testamentary trust. In general terms, a trustee needs to:

• [ ] Be at least the age of majority (18 in Ontario).
• [ ] Have the mental capacity to understand and carry out the responsibilities of the role.
• [ ] Not be under a legal disability that would prevent them from managing property, such as being subject to a guardianship of property themselves.

Beyond that, almost any capable adult can be named — a family member, a friend, a professional such as a lawyer or accountant, or a corporate trustee such as a licensed trust company. The trust document can also set out its own additional requirements, for example requiring a trustee to reside in a particular jurisdiction, and those requirements govern in addition to the general legal minimum.

Can a Beneficiary Also Be a Trustee?

Yes, and it is common — many family trusts name a parent as both a trustee and a beneficiary. What is not legally workable is a single trustee who is also the sole beneficiary of the entire trust, because a person cannot, in effect, hold property in trust for themselves alone; at that point there is nothing left to distinguish the trustee's role from simply owning the property outright. Where there is more than one beneficiary, or the trustee-beneficiary is only one of several people with an interest, this problem does not arise.

Individual Trustee vs. Corporate Trustee

An individual — a family member, friend, or professional — can serve as trustee, subject to the minimums above. A corporate trustee, generally a trust company, must be a properly licensed institution authorized to carry on trust business, rather than an ordinary corporation set up for another purpose. Families often default to an individual trustee for cost and familiarity reasons, and consider a corporate trustee where the trust will run for a long time, involves significant or complex assets, or where family conflict makes a neutral professional trustee more appealing.

Practical Qualities to Look For Beyond the Legal Minimum

• Financial literacy and organization. A trustee will need to keep records, file tax returns for the trust, and account to beneficiaries — comfort with paperwork and numbers matters.
• Impartiality. Where there is more than one beneficiary, a trustee has to treat them fairly according to the trust's terms, even when personal relationships make that difficult.
• Availability over time. Some trusts run for years or decades; a trustee needs to realistically expect to be available, or the trust document should provide a clear mechanism for replacing them.
• Willingness to get professional help. A good trustee knows when to bring in a lawyer or accountant rather than guessing, especially on tax filings, real estate, or a beneficiary dispute.
• Freedom from a direct conflict of interest. A trustee who has, or could develop, interests that clash with a beneficiary's should be considered carefully, even if they seem like the "obvious" choice within a family.

Naming More Than One Trustee

Some settlors name two or more trustees to act together — often a family member alongside a professional, or two family members balancing each other. This can add oversight and reduce the risk of one person acting alone, but it also means decisions generally need to be made jointly unless the trust document says otherwise, which can slow things down or create deadlock if the co-trustees disagree.
